however the name/title is clearly sourced from some sort of privileged condescension since it’s meant as an insult

The name was created by a woman who had no romantic fortune and who had accepted it. After that, though, actors like Steve Bannon realized that men in this population were especially easily manipulable, and so they started pumping out content for them. Instead of it being self-affirming in celibacy or helpful for younger generations navigating courtship, the content was designed to create a feedback loop so that the target group’s behaviors would reinforce their involuntary celibacy unintentionally, driving them further into despair and wallowing and further from solutions to their problems. There is nothing wrong with being unintentionally celibate. However, the “incel community” does not represent the entire involuntarily celibate population. It is used to refer to the community that consumes and distributes that specific type of content.

A good starting place is just to search Bannon and WoW gold farming. If you get lost in the rabbit hole, you can always return to Steve Bannon to get back on the trail again.
